ADJUSTABLE PIPE HANGER.

Application nled Hay 3, 1923. `Serial No. 686,843.

This' invention relates generally to -a means of support, such, for instance, as is particularly adapted for the suspension of overhead pipe lines of the kind commonly used in sprinkler stems for lire extinguishing purposes; an more particularly it is concerned with certain im rovements in a device of the hanger type t at is adjustable -towards and from the wall, ceiling, or other fixed support, to which it is attached.

The o jects of this invention, briefly summarized, are to provide a hanger for the purpose mentioned (1) that may be produced and installed at smalle remain in a fixed position of a justment; and (3) that will facilitate mounting of the pipe thereupon. Other objects, however, are also contemplated as will more fully hereinafter appear from the specification and claims.

One embodiment of this invention in a desirable form is illustrated :in the accompanying drawing wherein- Figure 1 is a front elevation of the hanger showing in longitudinal section its relation 'to the supporting bolt and to'a pipe which it is designed to carry; Fi 2 isa side elevation; and Fig. 3 is ap an view thereof.

It may be mentioned at the outset that the device of this invention is adapted for threaded connection with a bolt A which may be secured tol a wall, ceiling, or otherv fixed structure" by any ap ropriate means. The hanger itself consists o butthree parts, one being a sleeve B having a rotatable connection with a carrier C in the general form of a 'hook with which is associated a pivoted latch arm D.

The sleeve portion of the device, which is illustrated in ongitudinal section in Fig. 1, is provided as at with internal threads adapted to becengaged by the screw threads of the suporting bolt. Openings 11 may be arran ed upon diametrically opposite -sides of t e sleeve,` these being re erably elongated inthe direction of the s eeve axis,

' so as to aiord a view interiorly of the sleeve whereby its adjustment upon the bolt may be readil ascertained. Near the end of the sleeve w reconnection is made with the carrier C, is formed an annular shoulder 12 notched at intervals, as at 13, and adjacent thereto the sides of the sleeve may take-on' a polygonal formation vas at 14 so as to provide a wrench hold.

ense; (2 that will The end of the sleeve where connection is made with the carrier is formed to provide' a circular neck 15 which terminates in an enlarged head 16. Embracing this neck so as to swivel thereupon is a collar 17 which is joined-to the upper end of the carrier hook C to thereby connect the carrier to the sleeve.- Within the carrier may be seated a pipe E adapted to be placed therein by a lateral movement. A latch arm D is also provided to secure the pipe a ainst displacement and this may be pivote as at 18 to the hook end so as to have ca acity for swinging movement, as indicated y the dotted lines in Fig. 1. The free end of this arm terminates in the form of a finger 19 haying an inclined wedge :tace 20 adapted to rest upon an ob` liquely inclined wedge shoulder 21 formed upon one side of the collar.` The Enger' extremity is receivable within one ofthe notches 13, in which position it may be held bya bolt 22 which extends through a hole 23 traversing the free end of the arm and throu h a second hole 24 in register therewith ormedin a l1u 25 that is extended laterally from the col ar 17 adjacent the shoulder 2l.

In installingthe resent hangers connections are iirst ma e with the sup orting bolts, each sleeve being turned to adjust the device to the approximate hei ht desired.` Thereafter the pipe line is seate within the carrier supports and final adjustments made, following which each latch arm is swung to closed position with its finger extremity enagingi within the proximate notch 13.

houl any of the carrier supports have become bent during handling or installation, the same may easily be restored to correct position by swin 'ng the latch arm to locking osition and t en deliverin ree end as with the aid `o a hammer, to cause the inclined face 20 to work along the obli ue shoulder until the finger extremi is fugy received within the proximate note 13. ot only will such an operation result in realigning the carrier support to its intended position, but a registration of the two .holes 23 and 24 will be assured, thereby faof the b olt 22 which serves to maintain the arts in this relation for an indefinite perio of time. The several bolts 20, when applied in place, act both to lock each latch arm against the pipe, and to lock each carrierin adjusted position upon cilitating application a blow to its its associated sleeve. When so'installed the the principles of the invention, as de ined in the claims below, it is' to be deemed as within the scope of this patent.

I claim:

1. A pipe hanger in which is combined a sleeve and collar in swiveled relation, a carrier in the form of an open hook depending from the collar and integral therewith, a latch arm pivoted to the lower carrier end and movable to close the hook opening, an apertured lug extended laterally of the col- -lar, an apertured finger at the free endof the latch arm adapted to rest adjacent the lug, there being in the sleeve a notch where'- in a portion of the finger may releasably .engage, and means extended `throlu h the aperture of the lug and tin er where y to secure the latch arm to the co ar and prevent rotation of the sleeve relative thereto, substantially as described.

2. A pipe hanger in which is combined an inseparable swivelevd collarr and sleeve, the latter bein screw-threaded for adjustment upon the t reads of a support, a carrier of two interpivoted parts depending from the collar, a fixed connection between one carrier part andone side of the collar, means releasably connecting the other carrler part with the op osite co'llar side, and means on the sleeve with which the last named carrier part may releasablyengage to lock the colar from rotating relative to the sleeve, substantially as described.

3. A hanger in which is com rised a hook of two pivoted arms suitably s aped to embrace a pipe, a collar to which one arm is integrally joined, means on the collante which the other arm may be releasably conneeted, the free end ofY said last named arm being formed with a finger which extends past the collar, and a sleeve swivelly connected to the collarv having adjacent thereto a notch for receiving the finger'when its associated arm is in connection with the collar, the sleeve being thereby locked against
